Looking at the finer points of the contract, Develop has revealed that nearly every imaginable detail of Bungie’s four Destiny games has been negotiated with careful consideration. For instance, Bungie has “agreed to build a game it believes will fit within the parameters of a ‘Teen’ or ‘PEGI 16’” rating, despite the fact that all of Bungie’s Halo games other than RTS spinoff Halo Wars received an M rating.

Beyond that, oddities such as the number of Activision games each Bungie employee will receive as gifts per year (two) and the year Bungie can begin working on action shooters other than Destiny (2018) are also included. Rival studios Valve, Epic and Gearbox are “banned from developing any Destiny or Comet conversions or adaptations,” and Bungie will receive several bonuses depending on the performance of the Destiny franchise.

One other quirky point is that “Before commercial release of all games in the contract, Bungie must provide Activision with a list of Easter eggs it has spliced into the game. Activision, following the certification process, must provide Bungie with the same list.”

Details about Destiny will likely continue to emerge over the coming weeks, but for now you can study more information about the contract in our Destiny wiki.
